1. Introduction
Thank you for choosing the Scheppach MIX160 Concrete Mixer. This manual provides essential information for the safe and efficient operation, assembly, maintenance, and troubleshooting of your concrete mixer. Please read these instructions carefully before initial use and keep them for future reference. Proper use and maintenance will ensure the longevity and optimal performance of your machine.
2. Safety Instructions
Always prioritize safety when operating machinery. Failure to follow these safety guidelines can result in serious injury or damage to the equipment.
- Personal Protective Equipment (PPE): Always wear safety glasses, hearing protection, sturdy gloves, and appropriate work clothing. A hard hat and dust mask are recommended, especially when loading or unloading dry materials.
- Work Area: Ensure the work area is clear, well-lit, and level. Do not operate the mixer on unstable or slippery surfaces. Keep children and bystanders at a safe distance.
- Electrical Safety: Connect the mixer only to a grounded power outlet. Do not use extension cords that are damaged or improperly rated. Keep all electrical connections dry and away from water.
- Machine Stability: Before operation, ensure the mixer is stable and cannot tip over. The wheels should be chocked if necessary.
- Loading and Unloading: Never insert hands or tools into the drum while it is rotating. Use a shovel or other appropriate tools for loading and unloading materials.
- Maintenance: Disconnect the power supply before performing any maintenance, cleaning, or adjustments.
- Emergency Stop: Familiarize yourself with the location and operation of the ON/OFF switch for quick shutdown in an emergency.

4. Setup and Assembly
The Scheppach MIX160 Concrete Mixer requires some assembly before first use. Follow these steps carefully.
- Unpacking: Carefully remove all components from the packaging. Check for any damage during transit and ensure all parts listed in the packing list are present.
- Frame Assembly: Assemble the main frame components according to the diagrams provided in the separate assembly guide. Ensure all bolts are securely tightened.
- Wheel Attachment: Attach the wheels to the frame. Ensure they are properly secured to allow for safe movement.
- Drum Assembly: Mount the mixing drum onto the support shaft. Ensure the drum is correctly aligned with the drive mechanism.
- Motor and Gearbox Installation: Secure the motor housing and gearbox assembly to the frame. Connect the electrical wiring as instructed, ensuring all connections are tight and insulated.
- Tilting Mechanism: Install the tilting wheel/handle and ensure it operates smoothly, allowing the drum to be locked in various positions.
- Final Check: Before connecting to power, manually rotate the drum to ensure there are no obstructions and all moving parts operate freely. Double-check all fasteners for tightness.
5. Operating Instructions
Follow these steps for safe and effective operation of your concrete mixer.
5.1 Preparing for Mixing
- Position the mixer on a firm, level surface.
- Ensure the power cord is safely routed and connected to a suitable grounded outlet.
- Gather all necessary materials (cement, sand, aggregate, water) and tools (shovel, buckets).
- Tilt the drum to a suitable angle for loading using the tilting wheel.
5.2 Loading Materials
Always start the mixer before adding materials.
- Switch on the mixer using the ON/OFF switch.
- Add a small amount of water to the rotating drum first to prevent dry mix from sticking.
- Gradually add the aggregate (gravel), then sand, and finally cement. Add water intermittently as needed to achieve the desired consistency.
- Do not overload the drum. The maximum capacity is 160 liters, or approximately 114 kg of mixed material. Overloading can strain the motor and gears.

5.3 Mixing Process
Allow the materials to mix thoroughly until a uniform consistency is achieved. This typically takes a few minutes, depending on the mix design.

5.4 Unloading Mixed Material
- Position a wheelbarrow or container under the drum's opening.
- While the drum is still rotating, slowly tilt the drum downwards using the tilting wheel to discharge the mixed material.
- Once emptied, return the drum to its upright position.

6. Maintenance
Regular maintenance ensures the longevity and safe operation of your Scheppach MIX160 Concrete Mixer.
- Cleaning After Each Use: Immediately after use, clean the inside and outside of the drum thoroughly with water. Do not use abrasive cleaners or high-pressure washers directly on the motor housing. Allow the drum to rotate with water and some gravel for a few minutes to help dislodge hardened concrete.
- Motor Housing: Keep the motor housing clean and free from dust and debris to ensure proper cooling. The labyrinth casing is designed to protect against water splashes, but direct water jets should be avoided.
- Gears and Bearings: Periodically inspect the cast iron gears and other moving parts for wear or damage. Apply appropriate grease to the gear ring and pinion as needed to reduce noise and friction.
- Electrical Components: Regularly check the power cord and plug for any signs of damage. If damaged, have them replaced by a qualified electrician.
- Fasteners: Check all bolts, nuts, and screws periodically and tighten them if necessary. Vibration during operation can cause them to loosen.
- Storage: Store the mixer in a dry, protected area when not in use.
